As of 6th of January 2014, Fedora 19 has reached its end of life for
updates and support. No further updates, including security updates,
will be available for Fedora 19. A previous reminder was sent on
December 10th [0].
Fedora 20 will continue to receive updates until approximately one
month after the release of Fedora 22. The maintenance schedule of
Fedora releases is documented on the Fedora Project wiki [1]. The
Fedora Project wiki also contains instructions [2] on how to upgrade
from a previous release of Fedora to a version receiving updates.
